It is unlikely that this happened. So I am assuming corruption.
But I am able to query both the referred and referring table
successfully without any 'missing chunk' or similar errors that
usually indicate corruption.
Is it possible that corruption might cause data loss like this without
any errors?

How do I test for hardware problems? Are there any tools for this? I
am running PG on windows machine.

Thanks.
